Description

차량용 변속장치{POWER TRANSMISSION APPARATUS FOR VEHICLE} [0001] POWER TRANSMISSION APPARATUS FOR VEHICLE [0002]

본 발명은 차량용 변속장치에 관한 것으로서, 보다 상세하게는 3개의 싱크로나이저를 이용하는 DCT 구조에서 1개의 유성기어세트를 추가 적용하여 다단의 고정 변속단을 구현할 수 있고, 1개의 모터/제너레이터를 추가하여 발전과 토크 어시스트 및 전기자동차 모드 주행이 가능하도록 하여 연비 및 가속 성능을 향상시킬 수 있는 차량용 변속장치에 관한 것이다.More specifically, the present invention relates to a vehicular transmission, and more particularly, to a DCT structure using three synchronizers, one planetary gear set can be additionally applied to realize multi-step fixed transmission stages, and a single motor / Power assist, torque assist, and electric vehicle mode driving, thereby improving fuel consumption and acceleration performance.

차량에 있어서의 친환경 기술은 미래 자동차 산업의 생존이 달린 핵심 기술로서, 자동차 메이커들은 환경 및 연비 규제를 달성하기 위한 친환경 자동차 개발에 총력을 기울이고 있다.Eco-friendly technology in vehicles is a core technology with survival of the future automobile industry, and car makers are concentrating on developing environment-friendly vehicles to achieve environmental and fuel efficiency regulations.

상기 미래형 자동차 기술은 전기 에너지를 이용하는 전기 자동차(EV : Electric Vehicle), 하이브리드 전기 자동차(HEV : Hybrid Electric Vehicle), 효율과 편의성을 향상시킨 듀얼 클러치 변속기(DCT : Dual Clutch Transmission)를 예로 들 수 있다.The future type of automobile technology can be exemplified by an electric vehicle (EV), a hybrid electric vehicle (HEV) using electric energy, and a dual clutch transmission (DCT) with improved efficiency and convenience .

상기와 같은 미래형 자동차는 중량 및 원가 등 여러 가지 기술적인 제약이 있기 때문에 자동차 메이커에서는 배기가스 규제를 만족시키고, 연비 성능의 향상을 위한 현실적인 문제의 대안으로서 하이브리드 전기자동차에 주목하고 있으며, 이를 실용화하기 위해 치열한 경쟁을 벌이고 있다.Since such a future automobile has various technological limitations such as weight and cost, automakers pay attention to hybrid electric vehicles as an alternative to realistic problems to meet exhaust gas regulations and improve fuel efficiency. It is fiercely competitive.

하이브리드 전기자동차는 2개 이상의 동력원(Power Source)을 사용하는 자동차로서, 여러 가지 방식으로 조합될 수 있으며, 동력원으로는 기존의 화석 연료를 사용하는 가솔린 엔진 또는 디젤 엔진과, 전기 에너지에 의하여 구동되는 모터/제너레이터가 혼합되어 사용된다.A hybrid electric vehicle is an automobile using two or more power sources and can be combined in various ways. The electric power source includes a gasoline engine or a diesel engine using conventional fossil fuels, The motor / generator is mixed and used.

이러한 하이브리드 전기자동차는 저속에서 상대적으로 저속토크 특성이 좋은 모터/제너레이터를 주 동력원으로 사용하고, 고속에서는 상대적으로 고속토크 특성이 좋은 엔진을 주 동력원으로 사용한다.Such a hybrid electric vehicle uses a motor / generator having a relatively low torque characteristic at a low speed as a main power source and an engine having a relatively high torque characteristic at a high speed as a main power source.

이에 따라, 하이브리드 전기자동차는 저속구간에서 화석 연료를 사용하는 엔진의 작동이 정지되고, 모터/제너레이터를 사용하기 때문에 연비 개선과 배기가스의 저감에 우수한 효과가 있다.Accordingly, the hybrid electric vehicle has an effect of improving the fuel economy and reducing the exhaust gas because the operation of the engine using the fossil fuel in the low speed section is stopped and the motor / generator is used.

또한, 상기와 같은 하이브리드 전기자동차에 적용될 수 있는 변속기로서는 듀얼 클러치 변속기(Dual Clutch Transmission)를 하나의 예로 들 수 있으며, 상기 DCT는 수동 변속기 구조에 2개의 클러치를 적용하여 효율을 높이고, 편의성을 향상시킬 수 있다.As a transmission that can be applied to the hybrid electric vehicle as described above, a dual clutch transmission is one example. In the DCT, two clutches are applied to a manual transmission structure to improve efficiency and convenience .

즉, 상기 DCT는 클러치 2개를 적용하여 홀수단 및 짝수단을 번갈아 작동시키면서 변속이 이루어지는 변속기로서, 상기와 같이 홀수단 및 짝수단의 변속을 번갈아 작동시키는 매커니즘은 기존 MT(수동변속기) 및 AMT(자동화 수동변속기)가 가지고 있는 변속 시, 토크 단절감을 개선할 수 있다.That is, the DCT is a transmission in which a shift is performed while alternately operating the hole means and the even means by applying two clutches. As described above, the mechanism for alternately operating the shifting of the hole means and the even means is a conventional MT (manual transmission) (Automatic manual transmission), it is possible to improve torque disconnection.

그러나 상기 DCT는 발진 시, 클러치 슬립에 의한 클러치 소손 및 에너지 손실이 크고, 등판 발진 시, 클러치 슬립에 의한 후방 밀림이 과도하게 발생하여 안전상의 문제가 있으며, 클러치 열용량의 문제로 변속시간을 짧게 제어해야 하므로 자동변속기에 비하여 변속 충격이 크다는 문제점을 내포하고 있다.However, in the DCT, when the clutch is slipped, the DCT is disadvantageous in terms of the clutch disconnection and the energy loss due to the clutch slip, and the back slip due to the clutch slip occurs excessively during the back plate oscillation. And therefore, there is a problem in that the shift shock is larger than the automatic transmission.

또한, 상기 DCT는 하이브리드 전기자동차에 적용하기 위하여 전기 동력원인 모터/제너레이터를 효과적으로 배치하여야 하는 과제가 있다. In addition, the DCT has a problem of effectively arranging a motor / generator as an electric power source for application to a hybrid electric vehicle.

또한, 본 발명의 실시 예는 1개의 모터/제너레이터를 추가 배치하는 것만으로 전기자동차 모드 및 패러럴 하이브리드 모드로 주행이 가능하도록 하여 연비를 향상시킬 수 있는 차량용 변속장치를 제공하고자 한다.In addition, the embodiment of the present invention intends to provide a vehicle transmission capable of improving the fuel economy by allowing the vehicle to travel in the electric vehicle mode and the parallel hybrid mode only by additionally arranging one motor / generator.

상기 변속과정을 요약하면, 본 발명에 의한 변속장치는 전진 1속에서 4속까지는 상기 유성기어세트(PG)에서 감속되어 출력되는 회진동력을 고정 4속까지 변속하고, 전진 5속에서 전진 8속까지는 상기 유성기어세트(PG)에서 엔진(ENG)의 회전수와 동속으로 출력되는 회전동력을 고정 4속까지 변속하여 출력함으로써, 전체적으로 전진 8속과 후진 2속의 변속단을 구현할 수 있는 것이다.To summarize the shifting process, the transmission according to the present invention shifts the rotational power, which is decelerated and output from the planetary gear set PG to the fixed fourth speed, from the forward first speed to the fourth speed, , The rotational power output from the planetary gear set PG in synchronism with the rotational speed of the engine ENG is shifted to the fixed fourth speed so as to realize the forward speeds of the eight forward speeds and the reverse reverse speeds as a whole.

도 3은 본 발명의 제2 실시 예에 따른 변속장치의 모식도이다.3 is a schematic diagram of a transmission according to a second embodiment of the present invention.

도 3을 참조하면, 본 발명의 제2 실시 예에 따른 변속장치는 상기 제1 실시 예의 변속장치에 보조 동력원인 모터/제너레이터(MG)를 추가 배치하여 패러럴 하이브리드 모드 및 전기자동차 모드 주행이 가능하도록 차이점이 있다.Referring to FIG. 3, the transmission according to the second embodiment of the present invention further includes a motor / generator MG, which is an auxiliary power source, provided in the transmission of the first embodiment so as to be able to travel in parallel hybrid mode and electric vehicle mode There is a difference.

상기 모터/제너레이터(MG)는 공지와 같이 모터와 제너레이터 기능을 수행하며, 변속기 하우징(H)에 고정되는 스테이터(ST)와, 상기 스테이터(ST)의 반경방향 내측에서 회전 가능하게 지지되는 로터(RT)를 포함하여 이루어진다.The motor / generator MG functions as a motor and a generator, and includes a stator ST fixed to the transmission housing H and a rotor (not shown) RT).

상기 모터/제너레이터(MG)는 엔진(ENG)의 후측에 배치되어 상기 로터(RT)가 유성기어세트(PG)의 유성캐리어(PC)와 고정 연결된다.The motor / generator MG is disposed on the rear side of the engine ENG so that the rotor RT is fixedly connected to the planetary carrier PC of the planetary gear set PG.

이에 따라 엔진(ENG)의 구동력에 의한 전진 8속 및 후진 2속의 주행이 이루어질 때, 상기 모터/제너레이터(MG)의 토크 어스시트가 가능하여 패러럴 하이브리드 주행 모드가 가능할 수 있다.Accordingly, when the vehicle travels in eight forward speeds and two reverse speeds by the driving force of the engine ENG, a torque earth seat of the motor / generator MG is possible, thereby enabling a parallel hybrid driving mode.

그리고 모터/제너레이터(MG)의 구동력으로 전기자동차 모드(EV)로 주행하고자 할 때에는 상기 엔진 클러치(ECL)의 작동이 해제된 상태에서, 모터/제너레이터(MG)의 구동력만으로 주행이 가능하다.When the vehicle is to be driven in the electric vehicle mode EV by the driving force of the motor / generator MG, the vehicle can be driven only by the driving force of the motor / generator MG in a state in which the engine clutch ECL is released.

도 4는 본 발명의 제2 실시 예에 따른 변속장치의 변속 작동표로서, 변속과정을 살펴보면 다음과 같다.FIG. 4 is a table showing the shift operation of the transmission according to the second embodiment of the present invention.

또한, 전기자동차 모드(EV)에서는 모터/제너레이터(MG)의 구동력만으로 주행이 이루어져야 하기 때문에 후진의 동력전달경로는 엔진 클러치(ECL) 및 브레이크(BK)가 작동하지 않은 상태로, 상기 제1 실시 예의 후진 2속과 동일하게 이루어진다.In the electric vehicle mode EV, since the vehicle must be driven only by the driving force of the motor / generator MG, the reverse power transmission path is established in the state in which the engine clutch ECL and the brake BK are not operated, This is done in the same way as the second reverse in the example.

또한, EV 전진 1속 변속단(EV1)에서 EV 전진 4속 변??단(EV4)까지의 동력전달경로는 엔진 클러치(ECL) 및 브레이크(BK)가 작동하지 않은 상태로, 상기 제1 실시 예의 전진 5속 변속단(D5)에서 전진 9속 변속단(D9)까지와 동일하게 이루어진다.The power transmission path from the EV advancing first speed stage EV1 to the EV advancing fourth speed stage EV4 is a state in which the engine clutch ECL and the brake BK are not operated, Speed forward speed change stage (D5) to the forward speed change stage (D9).

이상에서와 같이 본 발명에 의한 제1 실시 예의 변속장치는 3개의 싱크로나이저를 이용하는 기존의 DCT 구조에서 하나의 유성기어세트를 추가 적용하는 것만으로 내부 구성을 간단하게 하면서도 전진 8속 및 후진 2속의 고정 변속단과 같은 다단화를 실현하고, 중량을 최소화 및 탑재성과 연비를 향상시킬 수 있다.As described above, in the transmission according to the first embodiment of the present invention, the internal structure is simplified by merely applying one planetary gear set in the conventional DCT structure using three synchronizers, It is possible to realize a multi-shoe such as a fixed speed-change stage, minimize the weight, and improve the mountability and fuel economy.

또한, 본 발명의 제2 실시 예에 따른 차량용 변속장치는 상기 제1 실시 예에서, 하나의 모터/제너레이터를 엔진 후측에 직렬 배치함으로써, 다단의 고정 변속단으로 엔진 모드, 패러럴 하이브리드 모드, 전기자동차 모드로의 주행이 가능하여 연비를 향상시킬 수 있다.Further, in the vehicle transmission according to the second embodiment of the present invention, in the first embodiment, one motor / generator is arranged in series at the rear side of the engine, so that the engine, the parallel hybrid mode, Mode can be traveled and the fuel consumption can be improved.
